My staking stopped working as well and now I can't even sync the wallet, tried deleting the chain but it just made it worse. Latest version, win 8.1. I'm not stressin' obviously, it's just a few thousand coins, but it'd be nice to at least get the wallet synced up haha.
What do you mean exactly tried deleting the chain?
Did you just try or did you actually delete something?
What did you delete exactly?
Should have completely deleted quotient roaming folder after saving your wallet.dat elsewhere.
